3、eration curve, Using themechanism motion and kinematics analysis diagram, the mechanism kinematicalprocess is analyzed which is laid a certain foundation for the further improvedcigarette pusher device.IntroductionPusher device is an important component in cigarette packaging machine. It has twoaspe

After completing two top fold Angle and cigaretteshorter edges; While keeping the al

Aluminum foil tobacco package under two top fold Angle and shorter edgesfolding is in motion, namely complete with reciprocating mode box back together in afold reciprocati

Slider-crank mechanism of reciprocating mode boxcontrol the reciprocating back and forth motion.Figure 1.

It is a kind of institution which can

9、 achieve precise trajectory. Cam-linkget the CAM and linkage mechanism of their respective advantages together, also caneliminate or reduce their some bad performance. This device can without error groundemersion given trajectory on the structure and function, and they can also finish thescope of mo

10、re than general four-bar mechanism. This paper studies the combinationmechanism with CAM mechanism and linkage mechanism with the implementationof the trajectory in figure 1 pusher device.As figure2 shows, component 1 is the original dynamic parts, the movement rulegiven by CAM; Component 2, 3, 4 fo

11、rm a four-bar mechanism, component part 5, 6,8, 9, form a five-bar mechanism which series with four-bar. The power also comesfrom the role of CAM- 2. Meanwhile slider-crank mechanism consolidate with theCAM which power is also from its output, the CAM mechanism in parallel withfive-bar mechanism, to

12、gether controlling the trajectory of pusher in F. Figure2 is thediagram for aluminum foil push the structure of smoking institutions pusher. the rod 2and rod 3, rod 3 and 4, pole 6 and pole 7, lever 1 and testing five are through pinconnection with the stem 4, component 5 as a whole part on the fram

13、e which can alsopromote the rotary motion of the pole 4 and rod 6. the points of F is the output ofinstitutions.Institutions movement analysisIn Pro/E the trajectory will change by adjustment of the length of five rods and theconnecting rod, the Angle between the institutions. In order to make the g

14、eologicalhazards in returning in design requirements, we first determine when the institutionsin various rods, and the center distance between the contact point in CAM roller CAMand CAM, ensure in contact for surface contact.Eventually get the crucible of track as shown in figure 1 shows. In Pro/E,

15、CAM speedcan be a constant value, also can be: slope, cosine, SCCA, cycloid, parabolic,polynomial, tables, user-defined3. By defining the CAM movement can get differentmotion characteristics, this paper take every minute 800 packet transmission motor(speed 400rad/min) as an example. Measurement helps understand and analyze theeffects of the mobile mechanism, and improves the information mechanism d
